Code Review

This pull request adds tests for the audio_in_video feature. A new end-to-end test is added for the Qwen2.5-Omni model to verify online serving with audio extracted from video. Additionally, a unit test is added to test_audio.py to verify the AudioMediaIO.load_bytes method's capability to extract audio from video bytes. The changes are a good addition, but there is a critical issue in the new end-to-end test where a local, hardcoded model path is used. This will prevent the test from running in other environments and needs to be addressed.
